Chris Hegedus and D.A. Pennebaker have crafted some of cinema's most impressive documentaries -- especially their musical documentaries like Monterey Pop -- but their look back at the titans of the soul genre comes off as flat and, frankly, lazy.

There's not a lot of setup for why this film is made -- though the half-assed reunion concert that concludes the brisk film comes off as even sillier than the one in Standing in the Shadows of Motown. In the beginning, our narrators state simply that they wonder what happened to pioneering soul singers like Wilson Pickett, Rufus Thomas, Jerry Butler, and The Chi-Lites. Turns out there's not a lot of mystery to it; they're still alive and kicking, and judging from the footage in the film, they're doing a lot of radio appearances. The exception is Isaac Hayes, who would go on to renewed fame by voicing the role of "Chef" on the South Park TV show -- and in fact it's Hayes that gets more screen time here than any of his compatriots.
